Is there a way to define an area or a distance for tooltips, so that
the user can click a bit off target and he will get the tooltip anyway?
no, there isn't.
But you can "clone" your thin lines using a use element and set the
stroke and fill to "none", increase the stroke-width and set the
"pointer-events" attribute to "stroke" (see
http://www.w3.org/TR/SVG11/interact.html#PointerEventsProperty). In the
original group you can set the pointer-events to "none".
